SWINGING CRADLE.

SPECIFICATION forming part of Letters Patent No. 643,267, dated February13, 1900.

' Application filed June 28,1899- Serial No. 722,168. (No model.)

and has for one object to provide a swinging cradle which is operated bya clock mechanism.

A further object is to provide a swinging cradle which can be operatedwithout attention for any predetermined length of time and which issimple in construction, effective in operation, and which can bemanufactured at a low cost.

To these ends the invention consists in a swinging cradle constructedand operated substantially as hereinafter illustrated and described, anddefined in the appended claims.

Referring to the drawings, in which similar letters of referenceindicate similar parts,

Figure 1 is a side view of the invention. Fig. 2 is a View inperspective of a detail of the construction.

In the drawings, A. represents the frame which supports the cradle 13and comprises two standards a and a and a connecting-bar of. Suitablestrengthening-braces a are arranged on each side of the standards togive the requisite rigidity to the frame. The upper ends of thestandards a and a are bent transversely and then downwardly, forming abracket or, which is perforated to receive a bolt 1), which serve aspivotal supports for the arms I) of the cradle 13. These arms B aresecurely bolted to the head and foot of the cradle and extend upwardly,the upper extremities of which are preferably curved so as to extendover the bracket a. The pivotbolts b pass through the curved end of thesupporting-arms b and through the perforations in the brackets a andthus permit the free swinging or oscillating movement of the cradle.Upon the standards a is fixed a clock mechanism 0 of any ordinary orpreferred form, the main spindle C of which terminates in a crank-leverC which is arranged so as to engage the inner sides of two segments D D,secured to a plate E, fixed to the cradlearm I). The segments D D areprovided with a curved end portion, which are oppositely arranged, sothat, as shown in Fig. 2, the inner sides form a recess or opening ofsubstantially oval shape, in which the crank-lever C works. The segmentsare secured to the plate E by means of threaded bolts passing throughthe straight portion of the said segments, and the said bolts extendthrough transverse slots formed in the plateE and are provided upontheir inner ends with binding-nuts by means of which the said bolts maybe fixed in their adjusted position. By means of this construction thesegments D D are capable of being adjusted so as to vary the size of theopening between them. The inner faces of the seg ments and also thecrank-lever may be covered with rubber or other suitable material toserve as a cushion, if so desired. The clock mechanism may be so set asto operate the cradle for any desired length of time. This mechanism isas well adapted for use with toy cradles for dolls as those of largermake, it being only necessary to vary the power of the clock mechanism.

While I have herein shown a preferred form of carrying my invention intoeffect, yet I do not desire to limit myself to such preferred details ofconstruction, but claim the right to use any and all modificationsthereof which will serve to carry into effect the objects to be attainedby this invention in so far as such modifications and changes may fallwithin the spirit and scope of my said invention.

I claim 1. In a swinging cradle, the combination with a frame, of acradle pivoted to swing in said frame, a clock mechanism mounted on saidframe, a crank-lever fixed on the end of the main spindle of said clockmechanism, a plate fixed upon said frame and segments adjustably securedto said plate and adapted to be engaged by said lever, whereby thecradle is operated, substantially as described.

2. In a swinging cradle, the combination with a frame, of a cradlepivoted to swing in said frame, a clock mechanism mounted on said frame,a crank-lever fixed on said frame, a plate secured to said frame, andhorizontally-arranged segments adjustably mounted upon said plate, eachof said segments having a hook end adapted to be engaged by saidcrank-lever, and a plane Working surface terminating in a curve uponwhich the end of the said lever is adapted to travel, substantially asdescribed.

In Witness whereof I have hereunto set my hand in the presence of twowitnesses.
